306 cabriolet turns over won't start

[Mighty306]

Hi Brocksey. Others on here will have more experience of immobilisers than me. I don't even know if it cuts both spark & fuel. Anyone? Am wondering if it's possible either the BSI (let's ECU know correct transponder is present in the key) or the ECU itself are either not powered or earthed properly. 6 years being idle in anything but good dry storage could play havoc with earth points in particular. Have you checked you have power to, say, the idle control valve or TPS? From memory they should show 5v on loom. If nothing the ECU may not be powered or earthed.

I can't hear the pump priming on my XSi it's that quiet. Hence question about pressure at rail.


Sorry if I'm stating lots of obvious stuff you've already thought of. Feel free to be honest!
